Use of units in physics

Introduction about physics and studying the subject This article is mainly about use of units in physics. But before going further let us first discuss about how to avoid problems that students face while studying physics. When you study physics you must have appropriate skills or you would have to struggle a lot while studying the subject. In my experience students fail to learn physics … Continue reading Use of units in physics »

Frequently used basic physics equations

This Article is about frequently used basic physics equations. I have covered most of physics equations for class 11 and 12. Earlier I had made a physics formula diary  which has been available for free download.  Now this Physics formulas and concepts pdf is little bit detailed in nature and there are the times when you study and you want most of your formulas in a page … Continue reading Frequently used basic physics equations »

Equilibrium and Potential energy

What is Equilibrium

A rigid body is supposed to be in equilibrium if there is no change in translational motion and no change in rotational motion
The general conditions for equilibrium are as follows
(i) The total force must be zero
(ii) The total torque about any axis must be zero.
In many cases it is convenient to consider torques about axes through the centre of gravity.

Types of equilibrium
We can divide the equilibrium into two categories With respect to the state of a body
1. Static equilibrium.
2. Dynamic equilibrium.

Newton’s Third Law of motion (action-reaction and examples)

This article is about in-depth explanation of newton’s third law of motion. Here in this article I presume that you have a introduction of Newtons first law of motion and Newton’s second law of motion. Now Newtons first law and second law of motion deals with the effect of forces when they acts on a body. First law is about the change in the velocity of the body on the application of unbalanced forces and second law is gives the exact amount of the force needed to produce a given acceleration.

Circular Motion Physics : Detailed explanation

Circular motion is a very important concept in physics. Here in this page I would like to go through the concept of circular motion. You encounter circular motion in your day to day life. Many rides in amusement parks undergoes circular motion. Curves on highway are part of a circle and cars making a tun undergoes circular motion. Merry-go-Rounds in playgrounds offer further examples of uniform circular motion. Now let us learn more about circular motion.

how to solve Simple Harmonic Motion(SHM) problems effectively

What is Periodic Motion : In Physics, a motion that is regular and repeating is called Periodic Motion. The time to complete one full motion is called the Time period of the Periodic Motion
What is SHM: A Simple Harmonic Motion is a special case of Periodic motion where a physical quatity varies sinusoidally.In this Periodic motion the restoring force is directly proportional to the displacement. The object oscillates between two position and Motion is sinusoidally in nature.
